When i was reading **http://www.space.com/scienceastronomy/russia_500days_041011.html** i wondered what kind of things will people have to pass on during the days they will be on the spaceship.


First,before i give my answer, i will explain what was the plan of the mission. Six Russian astronauts are going to be locked on a metal tube to experiment 500 days on a mock space station module to study how long mission to mars might afect its human crew. Volunteeres will be alowed to quit the experiment if they develop alimental or psychological stress.
The six astronauts will count with six tubes of oxigen and food, three tones of water. They will introduce several dificuties like, comunication lag. They woud be alowed to email the outside but with a deley of fourty minutes. Another dificulty is that not everyone speaks russian some of them speak russian.
"If we fail to understan each other, we will employ language body" Quipped Russian crew member, Sukhrob Kamalov.
Another dificulty that the crew members said that is not so important is the reletionshpi that they will get.
"Of course relations between the crew will not be harmonious, some will get on with others,others will not. But the priority is to be able to carry out tasks in spit of this, Alexander Suvorov "
"The most importan in a specially-developed tredmill , on wich a suit is attached via elastic pulleys. Instead of gravity, the runner has to strain aganist the tension of the pulleys.
Nasa was invited to be part of this fantastic experiment but an nasa guy said to a russian guy that they were pending so they get back of there idea.
